Men’s bodies make sperm and the fluids that make up semen on an ongoing basis. Sperm only make up a small portion of the volume of semen. Much of a man’s seminal fluids come from his prostate gland and other glands called the cowper’s glands and seminal vesicles.
Masturbation can actually help men learn to control the timing of their ejaculation. By practicing very specific masturbation techniques, you may be able to get more in touch with your body so that you can stop yourself from ejaculating before you’re ready.
Many men feel pressure in regard to their sexual performance with a partner. As a result, one of the more common questions that we get about sex has to do with learning to last longer during sex. With experience and practice, men often find that they can increase their control over the timing of their ejaculation.
I have always had problems lasting long during sex with my ex-girlfriends. Sometimes when I masturbate I will not feel like I have ejaculated yet and there will be semen-like stuff on my hand. Is that stuff on my hands before I ejaculate a problem? Also is there a way I can increase the time I last during sex?
